GENERAL ENGINE THROTTLE APPARATUS

Abstract:

A throttle apparatus includes a throttle body (12), a throttle valve (13), a throttle shaft (14), an electrically driven motor (15), a drive gear (23), a driven gear (24), a middle gear (25), and a sensor block (19). The middle gear (25) is held by the throttle body (12) such that a gear shaft is displaced from an imaginary straight line (V) connecting together a motor shaft and the throttle shaft (14). A gear arrangement projection part (34) that projects outward by a displacement amount of the middle gear (25) and a connector arrangement projection part (35) that projects to a same side as the gear arrangement projection part (34) at a position adjacent to a motor housing part (12b) side of the gear arrangement projection part (34) are formed on an outer surface of the throttle body (12). The motor connector (36) is arranged on the connector arrangement projection part (35) such that the motor connector (36) is in parallel with an axis center of the motor shaft and faces another end side of the throttle body (12). The sensor connector (20) is arranged on the sensor block (19) such that the sensor connector (20) is directed toward the axis center from a direction that is orthogonal to the axis center of the motor shaft.
